Tangkak district police chief Supt Mohad Idris Samsuri said the body parts of the victim, believed to be below 20 years’ old, were found by a resident.
The resident spotted an ankle part in the drain and immediately contacted the police at about 3.15pm.
Police conducted an investigation and later discovered five plastic bags containing other body parts.
“The victim’s head was not found in the bags. It was buried not far from where the body parts were found,” he told reporters at the scene last night.
Mohad Idris said the victim was believed to have been killed three days ago based on the state of decay and has not been identified.
He said a male suspect was arrested in a nearby area less than an hour after the body of the teenager was found.
“The suspect has no criminal record,” he said, adding that the case was being investigated under Section 302 of the Penal Code for murder.
The victim’s body has been sent to Tangkak Hospital for a post-mortem.
